The BACH-openModule is a full-featured solution for easy integration of most AES67-based control systems including Dante / RAVENNA / NMOS / Ember+ / LW+, and Ethernet AVB, all while protecting your investment from coming shifts in audio networking standards.
The BACH-openModule delivers unequalled performance with up to 512×512 channels of audio, latency is unrivalled at 125 us, and glitchless stream redundancy is always on without any compromise to channel count using dual-Gigabit Ethernet audio-over-IP interfaces.
ROSS’ comprehensive Product Development toolkit (PDK), complete with software and FPGA development tools, streamlines integration, dramatically lowering time to market and total-system-cost. The onboard dual-core ARM Cortex-A9 MPU includes its own Linux environment, enabling the development of custom embedded applications and FPGA cores for custom audio interfaces or processing.
